1 Claim.

This invention relates to an operator for jalousies and Venetian windows.

An object of this invention is to provide an improved operator for jalousies and Venetian windows whereby the slats may be readily adjusted and firmly secured or locked in their adjusted position.

Another object of this invention is to provide an operator which is designed to be attached to the frame of the jalousie or Venetian window and connected to the tie bar or link at one end of the slat structure so that the tie bar may be vertically adjusted and secured or locked in adjusted position.

A further object of this invention is to provide an operator of this kind which is simple in construction and will not readily get out of order.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawing and specification, and then more particularly pointed out in the appended claim.

In the drawing:

Figure 1 is a detail side elevation of an operator for a jalousie or Venetian window constructed according to an embodiment of this invention,

Figure 2 is a sectional view taken on the line 22 of Figure 1,

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Referring to the drawing, the numeral III designates generally a frame structure within which slats I I are pivotally mounted, and the slats II have disposed at each end right angular mounting plates I2 which are pivoted on pivots I3. The inner ends of the mounting plates 12 have pivotally connected therewith a vertically disposed connecting bar I4, the bar I4 being connected to the plates I2 by means of a pivot l5. Vertical movement of the bar I4 will provide for simultaneous rocking of all of the slats II.

In order to provide a means whereby the bar I4 may be vertically rocked and locked in adjusted position, I have provided an operator generally designated as I6. The operator I5 comprises a plate I! formed with a base flange I8 secured by fastening means I9 to the inner side of the frame I 0. The plate I! is of substantially semi-circular configuration at its inner end and is formed with an obtusely disposed flange 20.

A plate 2I is disposed in spaced relation to the inner portion of plate I'I, having a semicircular inner edge and an obtusely disposed flange 22 which is parallel with flange 20. Plate 2I is secured to plate I! by offsetting opposite portions of plate 2| as indicated at 23, and securing the offset portion 23 to the plate I! by fastening devices 24.

A tie bar operating lever 25 is pivotally secured between plates I1 and 2| on a pivot member 26 which engages through plates I1 and 2|. The outer end of lever 25 has pivotally mounted thereon a short link 21, and the link 21 is pivotally connected as at 28 to tie bar I4. The inner end of lever 25 is obtusely bent, as indicated at 29 and is externally threaded for receiving a locking nut or knob 30.

A substantially U-shaped washer M is mounted on the stud or bent inner portion 29 of lever 25 and the parallel sides 32 of washer 3t engage on the outer sides of flanges 20 and 22, as shown in Figure 2.

In the use and operation of this device the operator I6 is secured to the inner edge of frame In by the fastening devices l9, and link 2'! is pivotally connected to tie bar I4. Tie bar I4 is vertically moved and locked in adjusted position by partially unthreading knob or nut 30 and then rocking lever 25 upwardly or downwardly. When tie bar I4 is adjusted to position the slats I! in the desired position, knob or nut 33 is tightened so as to tightly bear washer 3! against the arcuate edges of flanges 20 and 22.

While plate I! is herein shown as being fastened to frame III by fastening devices passing through flange I8, in certain installations plate I? may be secured to frame It by fastening devices 24 which will hold the assembly together as well as secure the assembly to the supporting frame.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.

What I claim is:

In a jalousie or Venetian window structure having pivoted slats and a vertical tie bar connected to the slats, an operator for adjusting said slats, said operator comprising a plate, a right angular base flange carried by one end of said plate for attachment to a support, a semicircular obtusely angled flange carried by the opposite end of said plate, a second plate shorter in length than said first plate, a pair of offset members carried by said second plate, means securing said offset members to said first plate to thereby dispose said second plate in spaced 3 4 parallel relation to said first plate, a semi-circular REFERENCES CITED obtusely angled flange the timer end of Said The following references are of record in the second plate parallel with sa1d first flange, a me of this patent: lever between said plates, a pivot for said lever extending between said plates, an obtusely dis- 5 UNITED STATES PATENTS posed stud extending from said lever and en- Number Name Date gaging between said flanges, a nut threaded on 1, 51,753 Lane Sept. 1, 1925 said stud, a U-shaped washer on said stud be- 1,737,946 Rood Dec. 3, 1929 tween said nut and said flanges, a link pivotally 2, 09,384 Brown July 30, 1940 secured to the outer end of said lever, and means 10 2,479,602 Carani Aug. 23, 1949 pivotally securing said link to said tie bar. 2,506,771 Brown May 9, 1950 LUTHER OWEN CONNER. 2,53 ,499 Brown Nov. 28, 1950
